This undead flick begins with a young couple getting married. They drive to her Uncle's huge house, where they'll be staying for their honeymoon. While on the beach a zombie comes out of the water and drips disgusting goop on the guy. He starts having convulsions. She rushes him to the hospital but his heart stops and the doctor says "there's nothing I can do". But then he awakens, to everyone's surprise, and they assume it's faulty equipment. Soon, the husband kills someone, she freaks out, but doesn't leave him. Then, when he kills the next time, she helps him hide the body.
Basically, as the movie progresses, he gets more zombie-like and aggressive, until she has to defend herself against him. This isn't a bad movie but it proceeds exactly like you think it would, so there's no surprise or suspense whatsoever.
